If it were mine..
I'd fix what needs fixing and then finish it. That's what your Mother was trying to do (I'd guess).
Before my Mother passed away, she had given up on her quilting as it wasn't turning out right. Alzehimers is a cruel thing for people to endure. At one point, she handed me a quilt top she had been working on and said.."here, you finish this cause I can't make sense of it."
